The government is attempting to promote growth in the private sector by privatizing industries such as power and telecommunications. Saudi Arabia announced plans to begin privatizing the electricity companies in 1999, which followed the ongoing privatization of the telecommunications company. Shortages of water and rapid population growth may constrain government efforts to increase self-sufficiency in agricultural products.

In the 1990s, Saudi Arabia experienced a significant contraction of oil revenues combined with a high rate of population growth. Per capita income fell from a high of $11,700 at the height of the oil boom in 1981 to $6,300 in 1998. Increases in oil prices since 2000 have helped boost per capita GDP to $17,000 in 2007 dollars, or about $7,400 adjusted for inflation. Taking into account the impact of the real oil price changes on the Kingdom's real gross domestic income, the real command-basis GDP was computed to be 330.381 billion 1999 USD in 2010.

Oil price increases of 2008–2009 have triggered a second oil boom, pushing Saudi Arabia's budget surplus to $28 billion (110SR billion) in 2005. Tadawul (the Saudi stock market index) finished 2004 with a massive 76.23% to close at 4437.58 points. Market capitalization was up 110.14% from a year earlier to stand at $157.3 billion (589.93SR billion), which makes it the biggest stock market in the Middle East.‏

OPEC (the Organization of Petroleum Exporting Countries) limits its members' oil production based on their "proven reserves." The
